Urgent!!!!!

Need complete MATLAB code for this question, please respond as soon as possible, I will rate it as soon as I get the answer urgent!!!!!!!. Thank you in advance.

finddx.m

Write a function with the headerline

function $[dx]=$ finddx$(Y,$ limits$,$ actual, tol, method$)$

Where the user defined inputs are:

$Y$ is an anonymous function under which you want to find the area $($the integral$)$

For example, $Y=$@$(M)cos(M)+12$;

limits is a two element array specifying the limits of integration

For example, limits $=[-1,3]$;

actual is the actual value of the integral over the specified limit $($you can use wolfram alpha to determine this or use the provided examples$)$

For the example listed above, actual $=48\mathrm{.}983$;

tol is the tolerance $($how close you need to get to the actual integral before stopping the program and outputting $dx)$

For example, tol $=0\mathrm{.}1$

method is the method you want to use to calculate the integral this should be 'riemann', 'trapezoid', or 'simpson'

For example, method $=$ 'riemann';

You'll see below how we can compare strings in MATLAB to see if they are the same

The output of the function is:

$dx$ is the largest value of $dx$ you can use to calculate the integral within the tolerance using the given method $($i$.$e how thin do the rectangles

have to be to get an accurate enough calculation of the integral?$)$
